How many 7950s can I run on this power supply?

[Spekko]

id say up to 5,

i have a corsair AX750 with the following setup:
gigbyte ud5h mobo
intel i7 3770k cpu
1x 5970 - both cores at 830mhz
1x 5870 - currently at 901mhz
1x 7970 - at 1125mhz

been running stable for the last ~month also have 5 hard drives in the machine always on. i am able to game and mine with the 5870 perfectly aswell. seems perfectly stable so far, in the process of looking for a watt meter in my silly excuse for a country

3.
4 if you get under volt specific 7950's

7950s draw 200w, absolute maximum. If we're talking real power (Gold rated PSUs), then 1000w is more than enough for 3 cards. If you're using a budget or low power CPU (like Intel S and T processors) then you should be able to power 4 cards with a bit left over. I recommend the i5-3470T - at 35 watts you could easily run 4x 200w video cards.

Nooooo ... you are wrong.

7950 hogs way more than 200w max.

how many watts per card would I need to mine x11

3 cards for Scrypt, Scrypt-N, four cards of X11, X13

I love how we're giving answers to an OP who has not been on for 3 months 

For those newbies interested in mining a 7950 can be undervolted and would typically run just over 200W, so you could run 4 comfortably with scrypt.  The more energy efficient coins are even better.

One thing to consider though, every 10C of ambient air temp will pull another 10% of power form the card.  If you're running them in summer the resistance from heat and increased fan usage causes more power draw.  Hence winter rocks!

mine x11, x13 coins you can use as many cards as you can plug to it then.
